摘要： The present invention relates to a method for liquefying a fuel gas with a high methane content, which is a method that is a hybrid between an expansion method and a conventional open-cycle method. More specifically, the method according to the invention first of all compresses the cold medium then, in a first stage, uses the vaporisation thereof as cooling power and in a second stage expands to generate additional cold. The present invention also relates to a method for implementing the method according to the invention.

摘要： Refrigeration duty in a carbon dioxide purification unit (CPU) operating at elevated pressure and sub-ambient temperature can be provided in at least a first part by indirect heat exchange (162) against at least latent heat of at least one liquid first refrigerant (116,132), preferably carbon dioxide liquid(s) produced in the CPU, thereby typically evaporating the liquid(s), and a second part by indirect heat exchange with sensible heat energy alone of a second refrigerant (206). The second refrigerant may be nitrogen gas imported from an integrated cryogenic air separation unit (ASU) or carbon dioxide liquid exported from the CPU, cooled and returned to the CPU. One advantage is that total power consumption of the CPU and an integrated ASU is reduced.

摘要： The process and the apparatus serve for producing pressurized gaseous nitrogen by cryogenic separation of air in a distillation column system comprising a high pressure column (4), a medium pressure column (5), a main condenser (6) and a medium pressure column top condenser (7) both in the form of condenser-evaporators. A compressed and purified feed air stream (1) is introduced into under a first pressure and cooled in the main heat exchanger (2). At least a portion (3) of the air (1) cooled in a main heat exchanger (2) is introduced into the distillation column system. A first gaseous nitrogen stream (8) from the top the high pressure column (4) is condensed in the main condenser (6). Bottom liquid (16, 19, 21, 25) of the medium pressure column (5) is evaporated and gaseous nitrogen (30) from the top the medium pressure column (5) is condensed in the medium pressure column top condenser (7). Liquid nitrogen (53) from the medium pressure column (5) is pressurized (33) to a pressure which is at least equal to the high pressure column pressure and at least partially (36) introduced into the high pressure column (4). A second gaseous nitrogen stream (40) from the top the high pressure column (4) is recovered as pressurized gaseous nitrogen product. A portion (turbine stream 43) of the compressed and purified feed air stream (1) is workexpanded in an expansion machine (42) from the first pressure to a second pressure and afterwards is warmed in the main heat exchanger (2).

摘要： The present invention relates to a method and a device for completely condensing a process gas (P) by cryocondensation, comprising the following steps: cooling a gaseous cooling medium circulating in a cooling loop (10) by a liquid cooling medium in a main heat exchanger (11), whereby vaporizing the liquid cooling medium, feeding the vaporized cooling medium into the cooling loop (10) upstream of the main heat exchanger (11), cooling heat exchange surfaces (5) in a condenser (3) by the gaseous cooling medium circulating in the cooling loop (10), feeding the process gas (P) to be condensed into the condenser (3) to bring it into contact with the heat exchange surfaces (5) in the condenser (3), collecting the condensed process gas (P) as liquid product (LP) in a product container (8), and extracting gaseous cooling medium by an extractor (16) from the cooling loop (10) and guiding it through a pre-cooler (2) for pre-cooling the process gas (P) before feeding it into the condenser (3). The invention allows to completely condensate a process gas (P) by using the cold of a liquid cooling medium in three steps. In a main heat exchanger (11) the phase transfer from liquid to gas is used. In a second step the still very cold gas is introduced into the cooling loop (10), and in a final step the temperature difference between the cooling loop (10) after the heat exchange surfaces (5) in the condenser (3) compared to the environment (25) is mostly used in a pre-cooler (2). This highly efficient use of the cold allows using the process and the device according to the invention on an industrial scale for completely condensing a process gas (P).

摘要： Tiefkalte gasförmige oder verflüssigte Luft wird heute in der Regel großtechnisch erzeugt und über große Entfernungen zum Endabnehmer transportiert. Bei der Logistik sind jedoch besondere Sicherheitsmaßnahmen erforderlich, die die Wirtschaftlichkeit der Nutzung von tiefkalter bzw. flüssiger Luft insbesondere für kleinere und/oder fernab vom Erzeugungsort der flüssigen Luft gelegene Abnehmer drastisch absenken.
Erfindungsgemäß umfasst ein Verfahren zum Erzeugen tiefkalt gasförmiger oder verflüssigter Luft einen Wärmetauscher (27,21) zum thermischen Kontaktieren von Luft mit einem kryogenen Kältemittel (22,30) und einen Lufttrockner (26), in dem das beim Wärmetausch mit der zu kühlenden Luft verdampfte kryogene Kältemittel (30) als Betriebsmittel eingesetzt wird. Die Erfindung ermöglicht eine wirtschaftliche Bereitstellung von tiefkalter gasförmiger oder verflüssigter Luft auch bei kleineren Abnahmemengen.
